Abstract: A method is provided for forming a pattern of holes in a medium. According to an embodiment of the method, a pattern hole-transfer template is provided. The template has a first surface and a second surface opposite and facing away from one another, and a plurality of discrete circular apertures spaced apart from one another and extending through the template from the first surface to the second surface. The template is mounted on a medium. Then, a tool is inserted through the discrete circular apertures of the template and penetrated through the medium to form a pattern of holes in the medium. The template is separated from the medium.
